Filtering a primefaces datatable? - jsf

Question

I'm trying create a filter to one dataTable. I want that filter works with all keywords contained in datatable.
I am following examples at: http://www.primefaces.org/showcase/ui/data/datatable/filter.xhtml
but I can't do this works.
The problem is when I enter with any keywords the dataTable is clear showing message "No keyword found", if I delete keyword all results doesn't returns and message "No keyword found" keeps.
How can I solve this problem ?
Here how I'm trying.
XHTML
<p:dataTable id="tabelaAlunos" widgetVar="tableAlunos"
value="#{alunoMB.alunos}" var="x"
emptyMessage="No keyword found"
selectionMode="single"
selection="#{matriculaMB.aluno}"
rowKey="#{x.id}"
filteredValue="#{alunoMB.alunos}"
>
<f:facet name="header">
<p:outputPanel>
<h:outputText value="Filtrar: " />
<p:inputText id="globalFilter"
onkeyup="PF('tableAlunos').filter()"
style="width:150px" placeholder="Filtro"/>
</p:outputPanel>
</f:facet>
<p:column headerText="Nome">
<h:outputText value="#{x.nome}"/>
</p:column>
<p:column headerText="Sobrenome">
<h:outputText value="#{x.sobreNome}"/>
</p:column>
<p:column headerText="Endereço">
<h:outputText value="#{x.endereco.endereco}"/>
</p:column>
<p:column headerText="Número">

</p:column>
<p:column headerText="Unidade escolar">

</p:column>

Just add a filteBy for each column.
<p:column headerText="Nome" filterBy="#{x.nome}">
<h:outputText value="#{x.nome}"/>
</p:column>
